MACHINE FOR MAKING SUIT-CASE CORNERS- SPECIFICATION forming part of Letters Patent No. 788,408, dated April 25, 1905.

Application filed June 2, 1904. Serial No. 210,913.

To ail whom it rnrty concern:

Be it known that I, FREDERICK F. IvINs, a citizen of the United States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented a new and useful Machine for Making Suit-Case Corners, of which the following is a specification.

This invention relates to machines employed in the manufacture of articles of leather and other flexible material such as leatheroid, vulcanized fiber, and the like and has for its principal object to provide a mechanism wherein at,a single operation the articles may be shaped, trimmed, and ornamented in any desired manner.

Vith these and other objects in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the same.

In the accompanying drawings, Figure 1 is a plan view of a machine for making suit-case corners constructed in accordance with the invention. Fig. 2 is a central vertical section of the same. Fig. 3 is a view corresponding in part to Fig. 2, the drawing being on a somewhat larger scale and the partsin different positions. Fig. 4 is a detail perspective View of one of the cutting-knives detached. Fig. 5 is a similar view of the heading or embossing die detached. Fig. 6 is a similar view of the knife-carrying slide. Fig. 7 is a perspective view of one of the suit-case corners manufactured by the machine.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The machine forming the subject of the present invention is designed more especially for the manufacture of corner-pieces for suitcases, Satchels, and the like, or it may also be employed with suitable modifications in the shape of the dies and cutters in the manufacture of articles of any shape or size. The working parts are mounted on a suitable frame 1, comprising a plurality of standards connected at their upper ends by a table or platform 2, and from this table or platform extends a standard 3, carrying a guide 1 for a vertically-movable rack-bar 5, which carries at its lower end a male die 6 of acontour corresponding to the character of the work to be performed, the die in the present case being pyramidal in form. The teeth of the rack 5 intermesh with a pinion 6, carried by a short shaft 7 that is provided at its outer end with a hand-wheel 8, which may be turned to effect vertical movement of the rack and die. The guide 4 is threaded for the reception of a threaded end of a locking-bar 9, that may be turned until the threaded end of the bar engages the rack and holds the same in adjusted position.

On the bed 2 is an approximately triangular block 10, having three equidistantly-spaced radial arms 11, in each of which is a centrallydisposed radial slot 12. On the block is secured the base member 13 of the die, and above the base member and slightly spaced therefrom isa top plate 1 1, also forming a part of die, the two members constituting the female die and being held in place on the block by a plurality of bolts or similar securing devices.

On top of each of the arms 11 is secured a pair of guide-plates 15, which in connection with the upper face of the arms form guides for slidable plates 16, which are arranged at an oblique angle. To each of the slides 16 is bolted a shank 17 of the cutting-knife 18, the shank being provided with an elongated slot for the passage of the bolt in order to permit of adjustment of the position of the cutting edge of the knife and to take up wear from regrinding. The knife in the present instance is curved in the direction of the length of its cutting edge and fits snugly on top of the top plate 14: of the die, the latter also being curved, and said knife coacting with the edge of the pyramidal male die 6 in the trimming of the article after the shaping operation has been completed.

The knives are moved to cutting position by means of levers 18, pivoted near their upper ends by pins 19, that are carried by the radiated arms 11, the upper ends of the levers bearing against the end portions of the slides 16 and the lower ends of said levers being connected by links 20 to a vertically-guided treadle operated bar 21, which when depressed will simultaneously move all of the knives inward in the direction of the dies. WVhen released, the knives are returned to initial position by means of springs 22.

The article to be manufactured is in the present instance a corner-piece for suit-cases and the like and when finished has three sides the edges of which are arranged on curved lines, and in order to provide for the ornamentation of this corner-piece a number of beading-dies 23 are used, these producing a slight groove or indentation in the corner of the piece parallel with each of its edges.

The beading-dies 23 are in the form of small plates curved in cross-section and so shaped that they may be reversed and either end placed in working position. To the bottom of each beading-die is bolted a block 24, that is engaged by a pivotally-mounted cam 25, the latter being supported by a pin 26, carried by an arm 11. The upper end of each of the cams 25 enters a slot formed in the inner end of the slide 16, while the point of engagement of the cam with the block 24 is slightly below the top of said cam. The cutting-dies are guided between the sections 13 and 14 of the female die and their working edges may be projected within the limits of the die-spaces, so as to impress in the article a small groove or indentation. In the operation of the machine the leather or other material being operated upon is first saturated and then placed in position immediately over the die 4, after which the hand-wheel 8 is turned and the die 6 is depressed, forcing the material into the female die and completing the shaping operation. In order to hold the upper die in position, the locking-bar 9 is turned until the end of the same engages against the rack-bar 5. The treadle is then depressed, and thelevers 18 are forced inward until the cams 25 are engaged by the slotted ends of the slides 16, and said cams being forced inward will engage the blocks 24 and force the beading-dies to working position, the edges of said dies being projected slightly within the lines of the lower die and impressing or indenting the material held therein. The continued inward movement of the slide 16 will finally depress the cams 25 until the latter are wholly under the slides, and the cutting-dies will then act to sever the leather or other material that projects beyond the upper edges of the dies.

Having thus fully described the invention, what is claimed is 1. The combination with a female die, of a 7& 8,408

generally angular form in contour, a male die of similar contour, the edges of said dies at the completion of the forming operation being arranged in almement with each other, a maledie carrier of less cross-sectional area than said die, and leaving the entire edge of the die exposed, and a plurality of trimmers movable inward over the edges of the female and male dies. and serving to sever the material protruding beyond the edges of said dies.

2. The combination with forming-dies,of an auxiliary-die member arranged to impress or indent material held between the dies, and an independent operating mechanism for said auxiliary die.

3. The combination with forming-dies, of a second die for eifecting surface ornamentation on the material operated upon between said dies, and an independent operating mechanism for said auxiliary die.

4. The combination with a pair of formingdies, one of which has an opening within the line of its edge, an auxiliary die movable through said opening for indenting the mate rial held by said forming-dies, and an independent operating mechanism for said auxiliary die.

5. The combination with inner and outer forming dies, of a beading dieextending through the outer die for indenting the material held by the forming-dies, and an independent operating mechanism for said beading-die.

6. in combination, an outer die formed of a plurality of spaced members, an inner die, and an auxiliary die working between the members of the outer die.

7. The combination with a pair of formingdies, of a cutting-knife for the removal of surplus material, and a beading-die for indenting the material protruding from the edges of the dies held by the forming-dies at a point within the edges of said dies.

8. The combination with a pair of formingdies, of a trimming-knife, an auxiliary embossing-die, means for operating the formin dies, and means for successively operating the knife and the embossing-die.

9. The combination with a pair of formingdies, of a frame, a slide guided therein, a knife carried by the slide, an embossing-die arranged below the slide, and means for successively operating the embossing-die and the ICC IIO

slide to the die, and means for operating said slide.

12. The combination witha pair of dies, of a frame, a slide guided therein, a cutting-knife carried by the slide, a reversible embossing-- die for operating on the material within the edges of the dies, a block carrying the same, a cam for transmitting motion from the slide todthe vblock, and means for operating said sli e.

13. The combination with a supportingframe, of a female die formed in two sections, a male die, one of said dies being movable with respect to the other, a plurality of trimming-knives arranged at an angle oblique to the plane of movement of the die, a plurality of embossing-dies, parallel with the knives, means for transmitting movement from the knives to the embossing-dies, a treadle-rod, a lever, and a plurality of levers connecting the rod to the knives and serving to transmit movement thereto.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.
